This stalwart group contains many mixtures of colors, but the most powerful is the use of a single symbolic hue combined with omnipotent black. Black with scarlet, the ultimate ecclesiastical power color; black with regal purple or royal blue; black with yellow, the eye-riveting color combination of predatory beasts and stinging insects. Additional combinations include variations on black that still speak of authority – rock-solid charcoal gray or deepest blue. And two more power shades from the green family – the color of money and the military.
